RIVET AND NAIL FOR TRUNKS AND OTHER PURPOSES.

Specification of Letters Patent No. 3,048, dated April 15, 1843.

To all whom t may concern:

Be it known that I, LUTHER HoUGH'roN, of the city and countyvof Philadelphia and State of Pennsylvania, have invented a new and useful Improvement inthe Manufacture of Rivets and Nails for Trunks and for other Purposes, which is described as follows, reference being had to the annexed drawings of the same making part of this specification.

The cover E2 Figure 8 is made of thin sheet brass, copper, tin, or any other suitable material as represented at E2 Fig. 8 by being stamped or having the edges raised as seen at E2 Fig. 81.

The shank F Fig. 6 is made of a wrought or cut nail as may be required with a small head and inserted through an aperture in the center of a circular plate of sheet iron as represented at H Fig. 7 of sufficient thickness and of the diameter to lit in the cavity of the cover E2 Fig.r82 when placed therein, the head ofthe nail being between the inside of the coverE andthe plate H. The edges of the cover are then iattened'down over the circular plate irmly in the die by a falling hammer or other means, producing the form of nail (in its cross section) such as seen Vat Fig. 9. The head of the nail is thenraised in a die of any form or figure required by means of a convex form upon which the head of the nail is placed and a concave punch or drop which is dropped upon the head; or the head may be raised by means of a die and punch or in any convenient way. The nail is then burnished and finished.

Fig. 6 of the drawings is a side elevation of the shank and plate; Fig. 7 plan of the circular plate; Fig. 8 brass plate forming the cover and Fig. 82 the same with'the edges turned. Fig. 9 section of the nail when complete.

What I claim as my invention and which I desire to secure by Letters Patent is The before described method' of making rivets for trunks, that is to say the combina-f tion of the shank F plate H2 and cover D with the edges of the latter turned down over the plate H2, as set forth.

LUTHER HOUGHTON.
